Really? I would think some quality of life and polish would get a lot more people into the game. The amount of content in game already is a bit overwhelming at times. I think you guys just need a good advertisement push more than anything. A few sponsored steams on Twitch or something. Many of my friends had never even heard of the game.
For paper milling specifically:
There is simply no use for paper in the game yet, and as long as that is the case it stays as is. E.g. there simply is nothing planned for it yet, it's a WIP placeholder. Nor uncommon nor any sign of slow development.
